Error: Unable to make the session state request to the session state server

I have session configured in web.config this way:
<sessionState 
    mode="StateServer"
    cookieless="true",
    timeout="30" 
    stateConnectionString="tcpip=127.0.0.1:42424" /> 
ASP.NET State Service is started. 
 I got an error:
 Unable to make the session state request to the session state server. Please ensure that the ASP.NET State service is started and that the client and server ports are the same.  If the server is on a remote machine, please ensure that it accepts remote requests by checking the value of HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servicesspnet_state\Parameters\AllowRemoteConnection.  If the server is on the local machine, and if the before mentioned registry value does not exist or is set to 0, then the state server connection string must use either 'localhost' or '127.0.0.1' as the server name. 
And in system event log is message:
An error occurred in while processing a request in state server. Major callstack: ProcessCompletion-->ProcessReading. Error code: 0x80070057

 

If you running 1.1 and 2.0 make sure you installed the right one. 1.1 StateServer won't work with 2.0
